4. mphezi chitetezo equipotential kugwirizana;

5. Njira zotetezera;

6. Chitetezo champhamvu.

Chifukwa cha kuchuluka kwa mphamvu zama turbines amphepo ndi kukula kwa minda yamphepo, ntchito yotetezeka ya minda yamphepo yakhala yofunika kwambiri.

Zina mwazinthu zambiri zomwe zimakhudza magwiridwe antchito otetezeka a mafamu amphepo, kugunda kwamphezi ndikofunikira.Malingana ndi zotsatira za kafukufuku wa mphezi

chitetezo cha ma turbines amphepo, pepala ili likufotokoza momwe mphezi imagwirira ntchito, njira zowonongeka ndi njira zotetezera mphezi zamakina opangira mphepo.

Chifukwa cha chitukuko chofulumira cha sayansi ndi zamakono zamakono, mphamvu imodzi yokha ya makina opangira mphepo ikukula ndikukula.Ndicholinga choti

kuyamwa mphamvu zambiri, likulu kutalika ndi impeller awiri akuwonjezeka.Kutalika ndi malo oyika makina opangira mphepo zimatsimikizira izi

ndi njira yabwino yowomba mphezi.Kuphatikiza apo, zida zambiri zamagetsi zamagetsi ndi zamagetsi zimakhazikika mkati

makina opangira mphepo.Zowonongeka zomwe zimachitika chifukwa cha mphezi zidzakhala zazikulu kwambiri.Choncho, dongosolo lathunthu loteteza mphezi liyenera kukhazikitsidwa

kwa zida zamagetsi ndi zamagetsi mu fani.

1. Kuwonongeka kwa mphezi ku makina opangira mphepo

Kuopsa kwa mphezi kwa jenereta ya turbine yamphepo nthawi zambiri kumakhala pamalo otseguka komanso okwera kwambiri, motero makina onse opangira mphepo amakumana ndi zoopsa.

kugunda kwachindunji kwa mphezi, ndipo kuthekera kwa kugundidwa mwachindunji ndi mphezi ndi molingana ndi mtengo wapakati wa utali wa chinthucho.Tsamba

kutalika kwa makina amphepo a megawati kumafika kupitirira 150m, kotero mbali yamphepo yamphepo imakhala pachiwopsezo cha mphezi.A chachikulu

chiwerengero cha zida zamagetsi ndi zamagetsi zimaphatikizidwa mkati mwa fani.Tinganene kuti pafupifupi mtundu uliwonse wa zipangizo zamagetsi ndi magetsi

zida zomwe timagwiritsa ntchito nthawi zambiri zimatha kupezeka mu seti ya jenereta yamphepo, monga switch cabinet, motor, drive device, frequency converter, sensa,

actuator, ndi njira yofananira mabasi.Zidazi zimayikidwa pamalo ochepa.Palibe kukayika kuti kukwera kwa mphamvu kungayambitse kwambiri

kuwonongeka kwa makina opangira mphepo.

Zotsatira zotsatirazi za ma turbine amphepo zimaperekedwa ndi mayiko angapo aku Europe, kuphatikiza deta ya ma turbines opitilira 4000.Table 1 ndi chidule

mwa ngozizi ku Germany, Denmark ndi Sweden.Chiwerengero cha kuwonongeka kwa makina opangira mphepo chifukwa cha kugunda kwamphezi ndi 3.9 mpaka 8 pa mayunitsi 100 pa

chaka.Malinga ndi ziwerengero, ma turbines 4-8 ku Northern Europe amawonongeka ndi mphezi chaka chilichonse pama 100 aliwonse.Ndikoyenera

pozindikira kuti ngakhale zida zowonongeka ndizosiyana, kuwonongeka kwa mphezi kwa zigawo zolamulira kumawerengera 40-50%.

2. Kuwonongeka kwa mawonekedwe a mphezi

Nthawi zambiri pamakhala milandu inayi ya kuwonongeka kwa zida chifukwa cha mphezi.Choyamba, zidazo zimawonongeka mwachindunji ndi mphezi;Chachiwiri ndi

kuti kugunda kwa mphezi kumalowa mu zida zomwe zili m'mphepete mwa chingwe, chingwe chamagetsi kapena mapaipi ena achitsulo olumikizidwa ndi zidazo,

kuwonongeka kwa zida;Chachitatu ndi chakuti zida zogwiritsira ntchito zida zowonongeka chifukwa cha "kumenyana" ndi zomwe zingatheke pansi

ndi kuthekera kwakukulu komwe kumachitika panthawi ya mphezi;Chachinayi, zidazo zimawonongeka chifukwa cha njira yolakwika yoyika

kapena malo oyika, ndipo amakhudzidwa ndi magetsi ndi maginito omwe amagawidwa ndi mphezi mumlengalenga.

3. Njira zotetezera mphezi zamkati

Lingaliro lachitetezo cha mphezi ndiye maziko okonzekera chitetezo chokwanira chamagetsi amagetsi.Ndi njira yopangira ma structural

danga kuti apange malo okhazikika a electromagnetic compatibility mu kapangidwe kake.Mphamvu yosokoneza ya anti-electromagnetic yamagetsi osiyanasiyana

zida zomwe zili mumpangidwe zimatsimikizira zomwe zimafunikira pamlengalenga wamagetsi amagetsi.

Monga njira yodzitchinjiriza, lingaliro lachitetezo cha mphezi limaphatikizapo kusokoneza kwa ma elekitiroma (kusokoneza kwa conductive ndi

Kusokoneza kwa radiation) ziyenera kuchepetsedwa kukhala zovomerezeka pamalire achitetezo cha mphezi.Chifukwa chake, magawo osiyanasiyana amtunduwu

mawonekedwe otetezedwa amagawidwa m'malo osiyanasiyana oteteza mphezi.Kugawanika kwapadera kwa malo otetezera mphezi kumakhudzana ndi

Kapangidwe ka makina opangira mphepo, komanso mawonekedwe omangira ndi zida ziyenera kuganiziridwanso.Pokhazikitsa zida zotetezera ndikuyika

oteteza maopaleshoni, mphamvu ya mphezi mu Zone 0A yachitetezo cha mphezi imachepetsedwa kwambiri ikalowa ku Zone 1, komanso magetsi ndi magetsi.

zida zamagetsi mu turbine yamphepo zimatha kugwira ntchito bwino popanda kusokoneza.

Dongosolo loteteza mphezi lamkati limapangidwa ndi zida zonse zochepetsera mphamvu yamagetsi yamagetsi m'derali.Zimaphatikizapo makamaka mphezi

chitetezo cha equipotential, njira zodzitchinjiriza ndi chitetezo champhamvu.

4. mphezi chitetezo equipotential kugwirizana

Chitetezo cha mphezi kugwirizana kwa equipotential ndi gawo lofunikira la chitetezo chamkati chamkati.Kulumikizana kwa equipotential kungakhale kothandiza

kupondereza kusiyana komwe kungachitike chifukwa cha mphezi.Mu chitetezo cha mphezi equipotential bonding system, magawo onse oyendetsa amalumikizidwa

kuchepetsa kusiyana komwe kungakhalepo.Popanga ma equipotential bonding, gawo locheperako lolumikizana limaganiziridwa molingana

ku muyezo.Netiweki yathunthu yolumikizana ndi equipotential imaphatikizansopo kulumikizana kwa equipotential kwa mapaipi achitsulo ndi mphamvu ndi mizere yolumikizira,

yomwe idzalumikizidwe ndi busbar yayikulu yoyambira kudzera pachitetezo cha mphezi.

5. Njira zotetezera

Chipangizo chotchingira chingachepetse kusokoneza kwa ma elekitiroma.Chifukwa chapadera cha kapangidwe ka makina amphepo, ngati miyeso yotchingira ikhoza kukhala

amaganiziridwa pa siteji ya mapangidwe, chipangizo chotetezera chikhoza kuzindikiridwa pamtengo wotsika.Chipinda cha injini chidzapangidwa kukhala chipolopolo chachitsulo chotsekedwa, ndi

zida zofunikira zamagetsi ndi zamagetsi zidzayikidwa mu switch cabinet.Thupi la cabinet la switch cabinet ndi control

cabinet idzakhala ndi chitetezo chabwino.Zingwe pakati pa zida zosiyanasiyana mu nsanja ndi chipinda cha injini ziyenera kuperekedwa ndi zitsulo zakunja

chitetezo wosanjikiza.Pofuna kuponderezana, chotchinga chotchinga chimakhala chogwira ntchito pokhapokha mbali zonse ziwiri za chishango cha chingwe chikugwirizana ndi

equipotential bonding lamba.

6. Chitetezo champhamvu

Kuphatikiza pa kugwiritsa ntchito njira zodzitchinjiriza kupondereza magwero osokoneza ma radiation, njira zofananira zodzitchinjiriza zimafunikanso

kusokoneza conductive pamalire a zone chitetezo mphezi, kuti zida zamagetsi ndi zamagetsi zitha kugwira ntchito modalirika.Mphezi

Womangayo ayenera kugwiritsidwa ntchito pamalire a mphezi zone 0A → 1, zomwe zimatha kutsogolera mphezi zambiri popanda kuwononga

zida.Mtundu uwu wachitetezo cha mphezi umatchedwanso woteteza mphezi (Class I mphezi mtetezi).Iwo akhoza kuchepetsa apamwamba

kusiyana komwe kumabwera chifukwa cha mphezi pakati pa zitsulo zokhazikika ndi mphamvu ndi mizere yazizindikiro, ndikuzichepetsa ku malo otetezeka.Kwambiri

Makhalidwe ofunikira achitetezo cha mphezi ndi awa: malinga ndi mayeso a 10/350 μ S pulse waveform, amatha kupirira mphezi.Za

ma turbines amphepo, chitetezo cha mphezi pamalire a chingwe chamagetsi 0A → 1 chimamalizidwa ku mbali yamagetsi ya 400/690V.

M'dera lachitetezo cha mphezi komanso malo otetezedwa ndi mphezi, kugunda kwamphamvu kokha komwe kumakhala ndi mphamvu yaying'ono kumakhalapo.Mtundu uwu wa pulse current

amapangidwa ndi overvoltage yakunja yomwe imapangitsa kapena kuphulika kochokera ku dongosolo.Zida zodzitetezera zamtundu wamtunduwu wapano

amatchedwa surge protector (Class II mphezi mtetezi).Gwiritsani ntchito 8/20 μ S pulse current waveform.Kuchokera pakuwona kugwirizanitsa mphamvu, kuwonjezeka

chitetezo chiyenera kuikidwa pansi pa mtsinje wa chitetezo cha mphezi panopa.

Poganizira zakuyenda kwapano, mwachitsanzo, pa foni yam'manja, mphezi yamagetsi pa conductor iyenera kuyerekezedwa pa 5%.Kwa Kalasi III/IV

Chitetezo cha mphezi, ndi 5kA (10/350 μs).

7. Mapeto

Mphamvu ya mphezi ndi yaikulu kwambiri, ndipo njira yowombera mphezi ndi yovuta.Njira zodzitchinjiriza komanso zoyenera zoteteza mphezi zitha kuchepetsa

kutaya.Kupambana kokha ndi kugwiritsa ntchito matekinoloje atsopano kungateteze mokwanira ndikugwiritsa ntchito mphezi.Pulogalamu yachitetezo chamagetsi

kusanthula ndi kukambirana za dongosolo la mphamvu yamphepo kuyenera kuganiziranso kamangidwe kakambidwe ka mphamvu ya mphepo.Popeza mphamvu ya mphepo ku China ndi

kukhudzidwa ndi mitundu yosiyanasiyana ya nthaka, njira yokhazikitsira mphamvu yamphepo mu geology yosiyana imatha kupangidwa ndi magulu, ndi zosiyana.

njira zikhoza kutengedwa kuti zigwirizane ndi zofunikira zotsutsana ndi maziko.
